Could you please repost the image of the diagram... It doesn't display for me... Also... is the diagram for the m104 the same as the one for the m119?I have never had a problem with one I rebuilt.
Also here is a diagram that some people look for but can never find. I made it awhile back, apologies for the crudeness.
What size heat shrink did you use? Did you scrape off all the old insulation? Did you take apart the ETA at all or just shove the heat shrink down into the holes? I am going to rebuild mine, and reinsulating the wires seems reasonable.I've done it before and it works well - and much, much faster than new wires and soldering. I suspect the heat shrink tubing isn't as long lived as engine grade wire insulation but it's pretty good. The chances of it predeceasing the rest of the car are pretty small. I would never solder the butt joints though. I use NAPA uninsulated seemless butt joints, nice and small, with anti-oxidation paste, and stagger the joints so it doesn't look like a rat going through a snake. Adhesive lined HST over the joints is a nice touch, but 3M 33+ tape works well too.
